ABSTRACT In this project work, we are mostly concern about building a simple power streetlight which is automatically operated. There are four main components required to build a solar operated streetlight. The solar array, High efficiency D.C lamp section made by transistor, resistors, and the sensor LDR, changes controller which is made up of diode, resistors, LED, capacitor, and a battery of which the solar array is the most expensive. It is the solar array that produced a D.C voltage due ...
